Not clear documentation about setup of GCM Server during customization about iosched HOT 4 CLOSED

hey i am also facing the same problem. If you have figured out the steps can you please post them here?

from iosched.

You should be able to use gradle to interact with GAE:
cd gcm-server
[change build.gradle to point to your app id/email]
./gradlew.sh gaeUpdate

well i have used gradle..did gradle gaeUpdate ..the device is registered correctly but i get a problem in sending a notification..
There are a few doubts i have -

1. what has to be done with web-inf/classes/api.key.example file..do i have to write the my API key for Android there also?
2. there is a checkuser() method in Baseservlet which has some authentication code for google.com..do i have to make some changes there or leave it as it is?
3. when i go to my-app.appspot.com/admin and send a message from there..it says scheduleupdate.java not found..There is actually no file called scheduleupdate..so what should i do with it?

@mshukla19 take a look how it was solved in our case — gdgomsk@5b970ce.

For sending messages from server to mobile app you can use httpie tool (http://httpie.org/)

Several useful examples:

1. $ http POST https://your-app-gcm.appspot.com/send/global/test Authorization:key=top-secret message="Hello World!" -j -v
2. $ http POST https://your-app-gcm.appspot.com/send/global/sync_schedule Authorization:key=top-secret sync_jitter=0 -j -v
3. $ echo
   '{
   "format": "1.0.00",
   "audience": "all",
   "expiry": "2016-07-14T19:40:00Z",
   "title": "Title Goes Here",
   "message": "Message goes here testing 1234 foo bar qux",
   "minVersion": "1",
   "maxVersion": "201",
   "url": "http://www.google.com"
   }' |
   http POST https://your-app-gcm.appspot.com/send/global/notification Authorization:key=top-secret -j -v
4. $ echo
   '{
   "format": "1.0.00",
   "audience": "all",
   "expiry": "2016-07-14T19:40:00Z",
   "title": "Title Goes Here",
   "message": "Message goes here testing 1234 foo bar qux",
   "minVersion": "1",
   "maxVersion": "201",
   "url": "http://www.google.com",
   "dialogTitle": "Dialog Title",
   "dialogText": "Hello! This is a test dialog. Lorem ipsum dolor sit amet.",
   "dialogYes" : "Definitely!",
   "dialogNo" : "NO way!"
   }' |
   http POST https://your-app-gcm.appspot.com/send/global/notification Authorization:key=top-secret -j -v
